It matters in several ways.  First, if the initialization of one
data member relies upon the state of another, the latter must be
declared first such that it will be initialized first.  The order
of the initializer list doesn't matter; they are initialized in
declaration order.  However, keeping them in the same order in
the initialization as they are declared helps to reveal any
problems with initialization order, should that become an issue.

Second, many folks turn on all warnings and even make warnings be
errors to force that there be no warnings in their code.  Thus,
warnings such as gcc produces on this matter can be an error for
some.
